Audi A3

2105 Audi A3 Sedan. Installed the Curt Trailer Hitch Receiver 1-1/4". Had to drill out the front hole closer to the front of the car in the frame with a 1 1/3" step drill bit $12 to get the bolt and flat washer through the front hole. Only got 2 fish wires in package, so may (recommend) need to buy 2 more for the 7/16" bolt. Fish wiring takes a bit to get used to and don't loose the bolt in the frame(. Make sure the fish wire is really tightly screwed onto the bolt. Also bought the Yakima RidgeBack 2 Bike Rack 1-1/4" Tilting from etailer and as the picture shows it fits and looks great in the hitch.

Audi Parts has a nice 1 1/4" hitch cover with the 4 rings.

Thanks etrailer

2015 Audi A3

No problem with the hitch. I followed the online recommendation and received the correct hitch. Upon attempted install of the hitch, the mounting bolts could not be fished through the frame access holes. The bolt heads were too large. Upon calling customer service, I was informed that this occurs sometimes but offered no other recourse. Nowhere does it say on the website or in the installation instructions that there might need to be some drilling or reaming, as Joe B. and Don had to do per their reviews. Just the opposite, the website states no grinding or drilling. The website needs to update this to reflect the possibility of having to take the hitch to an installer if you're not comfortable with grinding and drilling. I don't have jacks nor do I want to buy a step drill bit to make the holes larger. The whole idea was to buy the hitch and mount it without extra work. Had I known this, I would have just taken the car somewhere and had it installed instead of losing time.

Sometimes it is necessary to file to enlarge access holes in order to get the hardware through.
-- Etrailer Expert Sierra K - 10/20/2021


Great hitch, used it for over a year. I pull a jet ski with it and it never gave me any issues

Audi A3

Hitch was a pain to install (would have been much easier with the car on a lift) but I knew going in it wouldn't be easy. The directions were good and I got it done. Hitch has worked perfectly for my wife's Audi A3 - we use it to attach a 1Up bike rack to it and it is rock solid. Worth a few hours of work to save several hundred bucks if I had it installed somewhere.

2015 Audi A3

We are happy to review this company. Despite the so called shipping delays, we did not experience this with E trailer. The service was easy and efficient.

2017 Audi A3

I needed a hitch to carry my bike rack for my Audi A3. The etrailer website made that easy. The site is easy to use, showed the two models that are made for my car, described the differences. I ordered it on line and got a confirmation of my order, then later the same day was informed it that already shipped. It arrived very well packaged.
While it says no drilling needed, I found the heads of the bolts would not quite fit through the access hole. I think due to undercoating of the car, so had to "ream" it out a bit. The products it great, looks great and performs perfect.


The hitch is perfect! Installation was pretty simple and who would’ve known there was a hitch for my Audi car. I thought I would never be able to carry my bikes as I wouldn’t put them on my roof or the trunk. Customer service was fabulous at helping answer all my questions. Cost was cheaper than a local camping trailer/hitch shop. Will definitely look to them again for my next purchase!

2010 GMC Jimmy

Overall - very satisfied. Over the last 10 years and 3 cars, this is my third hitch from etrailer and so far the easiest. The product was simple and easy to install. Spot on with the instructions and all the parts. Had to jimmy with getting the bolts in one side of the frame but no cutting or grinding required. Fit is very good - I'd like about 1/4 to 3/8 more rearward travel - but it does work with my old bike mount. Packaging was good - maybe a few less staples would still work. The Curt receive is built like a brick house with very clean welds and a nice finish.

2016 Audi A3

The hitch works great for our use (occaisional bike rack duty).
I happy to report it still looks new even after (1) New England winter.

After 2 New England winters I took a few minutes to scotch brite and touch up to look brand new. Only minor surface rust but wanted to keep it protected and looking new.
GaryS - 08/29/2018


Of course it took me twice as long to install
I expected, but I was able to do it without help. I love my hitch, it is almost invisible when looking at the car, and works perfectly.


Great hitch. Fits my 2015 S3.


Excellent instructions on the install and a great fit very happy with the purchase

2018 Audi A3

Perfect fit!! It took 20 minutes to ins tall.


Simply said as Fantastic. Order received as promised. The install instruction videos were great.


Fantastic service, great shipping! Haven’t used the actual hitch yet, but the company is great.

  • Hitch Installation on 2018 Audi A3
    The Class I hitches made for your 2018 Audi A3 (non e-tron version) are fairly easy no-drill installs, as hitches go. Both the Draw-Tite # 24930 and the Curt # C11399 are shown on the linked page. Both share the same capacities and both include all the hardware to bolt them to your car's frame. If you want to consider doing the install yourself you can review the linked instructions for these products and decide if it is something you want to tackle yourself. Tools required and the step-by-step...

  • Difference Between Draw-Tite and Curt Trailer Hitch for 2018 Audi A3
    Both the Draw-Tite Class I Sport Frame Receiver Hitch # 24930 and the Curt Class I Receiver Hitch # C11399 are confirmed to fit your 2018 Audi A3 as long as you don't have the e-tron model. These are extremely similar hitches that will attach to the Audi's frame at the same points meaning they will both sit in the same location under the vehicle's bumper when mounted. Both also have matching towing and tongue weight capacities of 2,000 pounds and 200 pounds respectively. As far as their...

  • Hitch Fits for 2016 Audi A3 Sportback
    I was able to find a fit for the 2016 Audi A3 Sportback, in a 1-1/4 hitch size. We offer the Curt # C11399 and the Draw-tite # 24930. If you end up going with the Curt you and plan on using the hitch for non-trailer loads like a bike rack or cargo carrier you will need a stabilization strap like # 18050. If you are looking for accessories for your hitch, I have linked our bike racks and cargo carriers that are compatible with the 1-1/4 hitch. All the hitches availale for your A3 are...

  • Comparing Curt and Draw-Tite Trailer Hitches for a 2016 Audi A3
    Curt # C11399 and Draw-Tite # 24930 hitches for the 2016 Audi A3 are comparable. Both meet industry requirements and undergo testing to ensure capacity and safety. The powder coat on the Curt hitches tends to be a little better and the Curt hitches are made in the USA. The Curt hitch also requires the use of stabilization strap # 18050 if using the hitch with anything other than a trailer such as a bike rack or cargo carrier per Curt's warranty requirements. Draw-Tite does not have that...

  • Comparing Curt and Draw-Tite Trailer Hitches For A 2019 Audi A3
    The Draw-Tite Class I Sport Frame Receiver Hitch # 24930 and the Curt Class I Receiver Hitch # C11399 have many similarities but I recommend the Draw Tite. The main reason for this is convenience because the Curt model recommends the use of a stabilizing strap for non-trailer uses like a bike rack. A great bike rack I recommend for the A3 to carry with the Draw-Tite hitch is the Curt # C18085 2-bike rack. It's lightweight and innovative design can carry a variety of bike frame designs...

  • Best Hitch and E-Bike Rack for 2018 Audi A3
    The hitch I suggest for your 2018 Audi A3 is the Draw-Tite # 24930. I recommend this Class I hitch because it easily bolts on with included hardware (no drilling) and because its main crosstube will be mostly hidden behind your rear bumper fascia for a clean look. Installation instructions are linked for you. Since you have fairly heavy e-bikes you'll need a special bike rack made for that extra weight. The rack that I recommend is the industry-leading Thule EasyFold # TH903202. The EasyFold...

    The correct hitch for your 2015 Audi A3 would be the Curt hitch part # C11399 that you referenced. For trailer wiring you would want the part # C59496. For a ball mount part # C45520, 1-7/8 inch ball # 19256, 2 inch hitch ball part # 19258.

  • Can Curt Hitches C11174 and C11399 Carry 150 lbs Worth of Bike Rack and Bikes
    Both the Curt hitches you referenced part numbers # C11174 and # C11399 have a 200 lb tongue weight capacity so they would work well with a bike rack setup that weighs 150 lbs with the Saris Freedom Superclamp EX part # SA4025F. You still have to use the stabilizer strap like part # 18050 since these racks are non-supported loads. One strap would be all that's necessary.

  • Trailer Hitch Recommendation for 2016 Audi A3 for Bike Rack
    If you want a trailer hitch for your 2016 Audi A3 that does not require the stabilizer strap when carrying a bike rack you would want the Draw Tite hitch part # 24930 which is a confirmed fit. The most popular bike rack we carry that has been confirmed to fit this vehicle is the Thule Camber 2 part # TH9058. We asked our demo and install guys to name their favorite, most easy-to-use bike racks and this one showed up in nearly everyone's top three. Check out the review video I attached...

  • Comparing the Curt and Draw-Tite Trailer Hitch Receiver for a 2016 Audi A3
    For your 2016 Audi A3 the correct part number for the Curt hitch is part # C11399 and the correct part number for the Draw-Tite hitch is part # 24930. Curt recommends using the Curt Trailer Hitch Support Strap part # 18050 to reduce chucking and jarring for all non-towing applications. The support strap must be used to abide by their warranty. The Curt hitch is made in the U.S.A whereas the Draw-Tite hitch is made in Mexico. Either hitch is a great option and will work well for you. If...

  • Trailer Hitch and e-Bike Rack Recommendations for a 2016 Audi A3
    For a hitch you can use the Curt Trailer Hitch Receiver # C11399 on your 2016 Audi A3 convertible and then for a bike rack I really like the Kuat NV 2.0 Base # BA12B. This is a wheel mount bike rack with a weight capacity of 60 lbs per bike so if your bikes don't have front fenders and you remove the battery on each (which I'm assuming the 125 lbs is with the batteries) this will work great! If you don't have large fenders you might be able to use the Saris SuperClamp EX Bike Rack # SA4025F...

  • Trailer Hitch and Wiring for a 2016 Audi A3
    For your 2016 Audi A3 I recommend Curt trailer hitch # C11399. This is a Class I trailer hitch with a 1-1/4 inch receiver rated for 200 pounds tongue weight and 2,000 pounds gross trailer weight. Be sure to check the owner's manual for the towing capacities of your vehicle and go by the lower rating. The recommended ball moutnt is # C45520 and for the pin and clip use # F-4. For a 1-7/8 inch ball I recommend # 19256 and for a 2 inch ball I recommend # 19258. And for trailer wiring I recommend...

    Yes, you can tow your jet ski trailer with your 2016 Audi A3; I checked the owner's manual and it is safe to tow your jet ski trailer with this vehicle. I do recommend checking your manual to verify the load limits, however. In order to tow there are a number of parts you will need, and I will list them below. - Curt Trailer Hitch Receiver # C11399 - Curt Drawbar for 1-1/4" Hitches # C45520 - 2" Hitch Ball # C40018 or 1-7/8" Hitch Ball # C40001 - Curt Hitch Pin and Clip # F-4 - ZCI...

  • Is There a Receiver Hitch Available for a 2015 Audi A3 Quattro
    Curt offers the Class I Receiver Hitch, # C11399, for your 2015 Audi A3 Quattro. This custom hitch is specially designed for your A3 and bolts to the frame with no welding required. For all non-trailer loads including bike racks, cargo carriers and so forth, Curt does require the use of Support Straps, # 18050. Failure to properly support these loads will void your hitch warranty from Curt. We no longer carry Bosal products, as they have given up operations in the US, so I do not have...

  • Trailer Hitch and Trailer Wiring Harness for 2015 Audi A3

I've linked to an install video showing this harness being installed on a 2014 A4. The procedure for your A3 will be different, but the video will give you a general idea of what the install will involve. For a hitch, I'd recommend the Curt # C11399 that you'd looked at.

    Both the Draw-Tite # 24930 and Curt # C11399 trailer hitches are similar for your 2019 Audi A3 (non e-tron) as far as weight capacities and designs go. The real differences lie in the restrictions attached to either trailer hitch for accessories. The Draw-Tite has a tab welded into the receiver tube which can be a fit issue for some 1-1/4" accessories while the Curt requires the use of a stabilizing strap like part # 18050 for all non-trailer accessories.

If you are wanting a really good bike rack for expensive bikes then I recommend installing a trailer hitch on your newer 2015 Audi A3 and using a hitch mount bike rack to avoid bike rack to vehicle contact, plus most of the hitch mount bike racks have more to offer.
